Steam for Linux

I don't have many Linux supported games, but Cogs is one of the supported 3d ones.However, it 'runs' (read: lags like crazy) at approximately 1 FPS, although I can play everything and crazier (Doom 3) on this HD 4000 fine (in Windows).

I am running Linux Mint 14 Cinnamon (Ubuntu 12.10), and I already got the packages that are mentioned here and there:

libgl1-mesa-glx is already the newest version.libgl1-mesa-glx:i386 is already the newest version.libgl1-mesa-dri is already the newest version.libgl1-mesa-dri:i386 is already the newest version.libgl1-mesa-dri:i386 set to manually installed.

Note that after the installation of steam.deb, but before updating, Steam Client pops up a weird window with a transparent body and in the middle a request to enter your password for installing some kind of required package. Any kind of weird popup that is different from expected password dialogs (e.g. gdebi) is what we all learn through knowledge and pain something that should never be acknowledged. So I answered cancel. I don't know what I cancelled, and I don't know if I already have that or how do fix that manually.
